1 Claim. (Cl. 229-34) My invention relates to a tray type single blankbox structure or cover capable of erection by automatic machinery from acollapsed state and including a pair of corner support means at eachcorner which provide an elevated support for a mating bottom sectioncontaining articles.

This application is a continuation-in-part of my previously filedapplication Serial No. 536,154, filed September 23, 1955 and entitled,Tray Type Collapsible Box Structure.

My invention provides opposed side walls operatively connected by forcetransmitting means to enable automatic set-up by machinery. Built intothis box structure without sacrifice of efiiciency and speed ofautomatic set-up are means for providing an elevated support, whichmeans is made up of corner supports hinged to side wall liner panels.These corner supports are swung into operative position during theset-up operation. Each corner of the box or cover structure has twocorner supports which abut each other and uniquely strengthen each otherto provide supporting pillars of unexpected strength.

Each pair of corner support means has proven to be an exceptionallyrigid structure due to a coaction between the elements thereof, thisbeing accomplished without any joining of the elements thereof.

Various other objects and meritorious features of the invention will beapparent from the following description taken in conjunction with thedrawings wherein like numerals refer to like parts throughout theseveral figures and wherein:

Fig. 1 is a plan view of a blank for a box structure with one end partlycut 011;

Fig. 2 is a plan view of a box structure made from the blank of Fig. 1and in collapsed condition ready for erection; this view is on reducedscale;

Fig. 3 is a perspective view of the box structure of Fig. 2 in erectedcondition with a broken away portion of a box positioned in the boxstructure in a product display position;

Fig. 4 is a sectional view taken on line 4-4 and rottated 90 degrees ofFig. 3 with the locking means in position for movement to the finallocked condition shown in Fig. 5;

Fig. 5 is a view similar to Fig. 4 showing the locking means in lockedcondition;

Fig. 6 is a top sectional'view taken on line 66 in Fig. 5; and

Fig. 7 is a sectional end view taken on line 7--7 of Fig. 3.

Referring now to Figs. 1-7, the box structure of my invention comprisesa main panel 14 and four side walls 15, 16, 17 and 18 integrally hingedat their inner edges to their respective edges of the main panel. Incollapsed condition ready for shipment the first pair of opposed sidewalls 16 and 18 is swung over the upper surface of the main panel asshown in Fig. 2. The second pair of opposed side walls need not be movedfrom the original condition in the blank forming the collapsed 2,852,178Patented Sept. 16, 1958 box structure which is shipped to the user.These walls 15 and 17 extend outwardly from and substantially coplanarwith the main panel 14.

The force transmitting means, broadly identified by numerals 60, 61, 62and 63, which facilitate the erection of the side Walls by a simplemanipulation of a single pair of opposed side walls, are integrallyhinged to the side edges 1920 and 2122 of the first pair of opposed sidewalls 16 and 18. When the carton is in collapsed condition as in Fig. 2,these force transmitting means extend outwardly over the second pair ofopposed side walls 15 and 17. Each force transmitting means has a linehinge (23, 24, 25, 26) directed toward its respective corner of the mainpanel, thereby forming an inner portion (27, 28, 29, 30) and an outerportion (31, 32, 33, 34). Each outer portion is swung into face-tofaceengagement with its respective inner portion and is then sandwichedbetween the inner portion and a predetermined portion of one of thesecond pair of opposed side walls 15 and 17 as seen in Fig. 2. Thisforms the box structure in collapsed condition ready for erection by theuser.

Line hinges (23, 24, 25, 26) form 45 degree angles with their adjacentside edges (19, 20, 21, 22) of the first pair of opposed side walls. Theouter portions (3134) of the force transmitting means are secured as byglue areas 35, 36, 37, 38 to their predetermined portions of the secondpair of opposed side walls.

The box structure is preferably erected by lifting the second pair ofopposed side walls 15 and 17 upwardly to the position shown in Fig. 4,this movement automatically erecting the first pair of walls 16 and 18through the action of the force transmitting means (60-63) describedabove.

To maintain the erected condition, locking means 39 and 40 areintegrally hinged to the outer edges of the second pair of walls 15 and17, these locking means preferably taking the form of liner panelshaving retainer lugs 43, 44, 45 and 46. The front wall 18 has a linerpanel 50 secured in face-to-face engagement therewith as by gluing asindicated in Fig. 1, the side edges of this liner panel being notched toprovide mating notches 51 and 52 for receiving the retaining lugs 43 and44, respectively. The rear wall 16 has a liner panel 55 secured inface-to-face engagement therewith as by gluing as indicated in Fig. 1,the side edges of this liner panel being notched to provide matingnotches 53 and 54 for receiving the retaining lugs 45 and 46,respectively.

As seen in Fig. 4, the liner panel 40 is in condition for downwardswinging movement into locked position, this position being shown inFig. 5 wherein the retaining lug 46 has swung degrees into lockingengagement with the notch 54.

As seen in Fig. 3, the box structure of Figs. 1, 2, and 47 isspecifically designed as a cover which can be inverted to provideelevated support for the article-carrying bottom section of the box andthereby provide an elevated display. This invention is particularlysuited for supporting heavy article-containing bottom sections as thedesign uniquely provides a double support at each corner. These doublesupports coact and rigidity each other as they are in face-to-faceabutting contact.

As seen in Figs. 1 and 2, inner corner support means 90, 90 and 91, 91are integrally hinged to the side portions of the liner panels 50 and55, respectively, the line hinges 92 of the corner support means beingpositioned inwardly of and parallel to the side edges of the linerpanels 50 and 55. As will be noted from Figs. 1 and 2, the cornersupport means 90, 90, 91, 91 extend beyond the side edges of the linerpanels.

In assembled condition as shown in Figs. 3-7, the corner support means90, 90, 91, 91 extend diagonally across the corners of the main panel 14and provide supporting surfaces "95 upon which the mating bottom section96 may rest. As seen in Fig. 3, the mating bottom section 96 has cutouts97 which hold articles 98 on display. In the structure shownslots 99 areprovided in the upper corners of the mating bottom section for receivingthe corner supporting means 90, 90, 91, 91 when the cover is placedonthe bottom section.

Outer corner support means 93, 93, 94, 94 are integra'lly hinged-to theside portions of locking means 39 and 40, the line hinges 92 of thecorner support means being positioned inwardly of and parallel to theside edges of the locking means 39 and 40. It will be noted thatthecorner support means 93, 93, 94, 94 extend beyond'the side edges of thelocking means.

As seen in Fig. 4-, the corner support means 91 is forced into properposition across the corner of the box when the side walls of the box arebrought into vertical position. When the locking means 40 is swung downinto the box, the corner support means 94 is brought into face-to-faceabutting engagement with the previously positioned corner support means91 as shown in Figs. 5, 6 and 7. This rigidifies the corner supportingstructure at each corner of the box and provides supporting pillars ofgreat strength capable of supporting heavy loads. The

hinge lines 92 are scored in a manner such that the corner support means90, 91, 93, 94 are biased back toward their original position, therebyaiding in the establishment of good abutting contact between each pairof corner support means.

Various other modified forms of the invention will be apparent from theforegoing description and for that reason I wish to limit myself onlywithin the scope of the appended claim.

I claim:
